Casio fx-991ES PLUS-2 Natural Display Scientific Calculator

The Casio fx-991ES PLUS-2 is a non-programmable scientific calculator built to make everyday math clearer. Its Natural Textbook Display shows fractions and equations the way they appear in your textbook, so you spend less time decoding results and more time understanding them.

From school algebra to college-level statistics, this casio calculator handles equations, matrices, vectors, complex numbers and integration in a slim 95 g body. Solar and battery power keep it ready for class, study sessions and exams.

Key Features

• Natural Textbook Display: Equations and results appear exactly as printed in textbooks. This makes answers easier to read and check.

• 10+2 digit dot matrix display: The clear LCD shows detailed results, which helps you spot mistakes quickly.

• Wide math coverage: It supports equation, integration/differential, matrix, vector, complex number and base-n calculations. One calculator can cover many subjects.

• Statistics tools: The list-based STAT data editor, standard deviation and regression analysis let you work with data sets without lengthy manual steps.

• CALC and SOLVE functions: You can reuse an expression with different values or solve for an unknown. This saves time on repeated problems.

• Table function: Generate a table of values from a function to understand how it behaves.

• Random integers, fractions, combination and permutation: These cover probability, counting and everyday classroom calculations.

• 9 variables and multiple memories: Independent memory (M / M+ / M-), answer memory and memory protection let you store values and reuse them safely.

• Fast-typing function (2-key rollover): Quick keying is registered reliably, so fewer key presses are missed.

• Solar and battery power: The main battery lasts approximately 3 years, and auto power off saves energy between uses.

• Slim and lightweight: At 161.5 × 77 × 11.1 mm and 95 g, it slips easily into a school bag or pocket.

• Slide-on hard case: The case protects the keys and display while you travel.
